  • O-GlcNAcase (OGA) is a family 84 glycoside hydrolase catalyzing the hydrolytic cleavage of O-linked β-N-acetylglucosamine (O-GlcNAc) from serine and threonine residues of proteins. Thus far, three forms of OGA have been identified in humans. Here we optimized the expression of these isoforms in E. coli and characterized their kinetic properties. Using Geno 3D, we predicted that N-terminal amino acids 63–342 form the catalytic site for O-GlcNAc removal and characterized it. Large differences are… CONTINUE READING
